Lulz - that’s all well and good, except that gets paid mostly lip service even by the professional militaries, who are the ones who have the most to lose by not following the rules.

Civilians do what they need to do to survive and protect their loved ones. If that means shivving a soldier in the back while pretending to be unarmed, so be it.

Having guns is way better than civilians usually get.

Unlawful combatants aren't protected by the laws of war, they're protected by the laws of the land they are in. I think you'd be surprised at how lenient the laws of the land can be for people who technically commit crimes like murder against invading forces.
